C#版Windows服务安装卸载小工具

前言
 在我们的工作中，经常遇到Windows服务的安装和卸载，在之前公司也普写过一个WinForm程序选择安装路径，这次再来个小巧灵活的控制台程序，不用再选择，只需放到需要安装服务的目录中运行就可以实现安装或卸载。 

开发思路
1、由于系统的权限限制，在运行程序时需要以管理员身份运行
2、因为需要实现安装和卸载两个功能，在程序运行时提示本次操作是安装还是卸载  需要输入 1 或 2 
3、接下来程序会查找当前目录中的可执行文件并过滤程序本身和有时我们复制进来的带有vhost的文件，并列出列表让操作者选择（一般情况下只有一个）
4、根据用户所选进行安装或卸载操作
5、由于可能重复操作，需要递归调用一下
具体实现
首先们要操作服务，需要用  System.ServiceProcess 来封装实现类 

using System;
using System.Collections;
using System.Configuration.Install;
using System.Linq;
using System.ServiceProcess;

namespace AutoInstallUtil
{
  public class SystemServices
  {
    /// <summary>
    /// 打开系统服务
    /// </summary>
    /// <param name="serviceName">系统服务名称</param>
    /// <returns></returns>
    public static bool SystemServiceOpen(string serviceName)
    {
      try
      {
        using (var control = new ServiceController(serviceName))
        {
          if (control.Status != ServiceControllerStatus.Running)
          {
            control.Start();
          }
        }
        return true;
      }
      catch
      {
        return false;
      }
    }


    /// <summary>
    /// 关闭系统服务
    /// </summary>
    /// <param name="serviceName">系统服务名称</param>
    /// <returns></returns>
    public static bool SystemServiceClose(string serviceName)
    {
      try
      {
        using (var control = new ServiceController(serviceName))
        {

          if (control.Status == ServiceControllerStatus.Running)
          {
            control.Stop();
          }
        }
        return true;
      }
      catch
      {
        return false;
      }
    }

    /// <summary>
    /// 重启系统服务
    /// </summary>
    /// <param name="serviceName">系统服务名称</param>
    /// <returns></returns>
    public static bool SystemServiceReStart(string serviceName)
    {
      try
      {
        using (var control = new ServiceController(serviceName))
        {
          if (control.Status == System.ServiceProcess.ServiceControllerStatus.Running)
          {
            control.Continue();
          }
        }
        return true;
      }
      catch
